CommonUnits

CommonUnits[{quantity1,quantity2,…,quantityn}]

在可兼容维度上，把 quantity1 到 quantityn 转化为常见单位.

更多信息

  • 对具有共同维度的输入单位的每个子集，CommonUnits 把输入列表的单位转化为一个常见单位.
  • CommonUnits 使用启发式方法决定最适合输入数据的单位.
  • 设计货币单位的操作要求互联网是连接的.

范例

打开所有单元 关闭所有单元

基本范例  (2)

把长度列表转化为常见单位：

Wolfram Language code: CommonUnits[{Quantity[2, "Feet"], Quantity[30, "Inches"], Quantity[0.25, "Meters"]}]

把所有长度和质量组成所有单位转化为一个常见单位：

Wolfram Language code: CommonUnits[{Quantity[10, "Feet"], Quantity[300, "Inches"], Quantity[45, "Pounds"], Quantity[12.2, "Kilograms"]}]

范围  (4)

对一列 Quantity 对象使用 CommonUnits：

Wolfram Language code: CommonUnits[{Quantity[3.2, "Meters"], Quantity[10, "Inches"], Quantity[7, "Feet"]}]
Wolfram Language code: CommonUnits[{Quantity[3.5, "Kilograms"], Quantity[3.5, "ChineseJins"], Quantity[3.5, "Pounds"]}]

对 QuantityArray 对象使用 CommonUnits：

Wolfram Language code: qa = QuantityArray[Transpose@{Range[100], Range[100]}, {"Meters", "Inches"}]
Wolfram Language code: CommonUnits[qa]

CommonUnits 可以换算具有 IndependentUnit 规范的量：

Wolfram Language code: qa = Quantity[5, "Kilo"IndependentUnit["Apples"] / "Meters" ^ 2]
Wolfram Language code: qb = Quantity[300, IndependentUnit["Apples"] / "Feet" ^ 2]
Wolfram Language code: CommonUnits[{N[qa], qb}]

CommonUnits 可以换算混合量：

Wolfram Language code: qa = Quantity[MixedMagnitude[{1, 80}], MixedUnit[{"Meters", "Centimeters"}]]
Wolfram Language code: qb = Quantity[MixedMagnitude[{5, 10}], MixedUnit[{"Feet", "Inches"}]]
Wolfram Language code: CommonUnits[{qa, N[qb]}]

属性和关系  (3)

CommonUnits 转换具有相同 UnitDimensions 的量：

Wolfram Language code: CommonUnits[{Quantity[0.5, "Teslas"], Quantity[200, "Gausses"], Quantity[10, "Webers"/"Dekameters"^2]}]
Wolfram Language code: UnitDimensions /@ {Quantity[0.5, "Teslas"], Quantity[200, "Gausses"], Quantity[10, "Webers"/"Dekameters"^2]}

CommonUnits 作用于具有相同 UnitDimensions 的量的子集上：

Wolfram Language code: CommonUnits[{Quantity[3., "Meters"/"Seconds"], Quantity[0.23, "Kilograms"], Quantity[40., "Miles"/"Hours"], Quantity[6.5, "Pounds"]}]
Wolfram Language code: GroupBy[{Quantity[3., "Meters"/"Seconds"], Quantity[0.23, "Kilograms"], Quantity[40., "Miles"/"Hours"], Quantity[6.5, "Pounds"]}, UnitDimensions]

CommonUnits 将无单位量纲的量转换为纯数：

Wolfram Language code: {Quantity[7, "Percent"], Quantity[3, "Dozens"], Quantity[34, "PartsPerMillion"]}
Wolfram Language code: %//CommonUnits
